pmv will apply the given Perl expression to each of the
file names. If the result is different from the original name, the
file will be renamed, linked, or symlinked.
If the expression is any of uc, lc, of ucfirst, pmv will DWIM.
pmv is a wrapper around File::PerlMove, which does most of the work.
EXAMPLES
To change editor backup files back to Perl sources:
$ pmv 's/\.bak$/.pl/' *.bak
foo.bak => foo.pl
bar.bak => bar.pl
Lowcase file names:
$ pmv lc *JPG
Shift numbered examples to a new section:
$ pmv --reversed 's/^ex(\d)/"ex".($1+3)/ge' ex*
ex42.dat => ex72.dat
ex25.dat => ex55.dat
ex22.dat => ex52.dat
ex13.dat => ex43.dat
ex12.dat => ex42.dat
Note that these need to be processed in reversed order, to prevent
ex12.dat => ex42.dat botching with the exisitng ex42.dat.
